Both devices will also come with a camera upgrade. Apple needs to excite fans with this new device in order to help boost their stock price back up.

Apple's stock recently plunged close to the $400 mark, however, that should rise as the unveiling of the new iPhone approaches. The front camera on the new handset also might be upgraded to 2 megapixels, and both the front and rear shooters should be capable of simultaneously recording or taking photos.

This will be similar to the dual-cam mode that is found on the Galaxy S4 and LG Optimus Pro.

Both new models have been predicted to help Apple to surpass Android's market share by the year 2015, according to new data.

In a recent survey of 16,000 U.S. smartphone users, 91 percent of current iPhone owners plan to buy the next-generation version once they are eligible for an upgrade. Out of the Android users surveyed, only 76 percent plan to purchase another device running Google's software.

The data was compiled by the Yankee Group, who believes that Apple's consistent customer loyalty will allow the company to surpass its fiercest competitor in two years time. Android users do not feel as strongly about the Google brand. Three quarters of those looking to ditch Android plan to purchase an iPhone when they decide to upgrade.

"Think of the Apple and Android ecosystems as two buckets of water. New smartphone buyers- mostly upgrading feature phone owners- fall like rain into the two big buckets about equally, with a smaller number falling into Windows Phone and BlackBerry buckets," wrote the Yankee Group. "However, the Android bucket leaks badly, losing about one in five of all the owners put into it."
